【摘要】 为减少煤矿生产中安全事故的发生，从情绪控制角度，基于效价-唤醒度(V-A)情绪模型，并结合情绪唤醒方法和生理测量技术，开展矿工安全行为能力认知试验；然后通过测量不同情绪唤醒下的注意力和决策时间，采用回归分析法，探究不同情绪效价下唤醒度对矿工安全行为能力的影响。结果表明：低唤醒度正性情绪中，唤醒度的降低会使矿工注意力减弱、决策时更厌恶风险；在正性情绪的高唤醒度区间，随着唤醒度的提高，矿工注意力和决策厌恶风险程度先增加后减少，直到低于中性情绪；低唤醒度负性情绪中，唤醒度降低会使矿工注意力和风险厌恶程度都降低，在负性情绪的高唤醒度区间，唤醒度的提高同样使注意力和决策的风险厌恶程度先增加后减少，甚至直到低于中性情绪；相较之下，在情绪的高唤醒度区间，正性情绪唤醒度的提高更容易使矿工安全行为能力降低到中性情绪水平以下。更多还原

【Abstract】 In order to reduce the occurrence of safety accidents in coal mine production, from the perspective of emotion control, based on Valence-Arousal(V-A) emotional model, combined with emotional arousal methods and physiological measurement techniques, a cognitive experiment of miners’ safety behavioral competence was conducted. Attention and decision-making time under different emotional states were measured. The regression analysis was used to investigate the continuous effects of degree-of-arousal on attention and risk preference under different emotional valence. The results show that in low degree-of-arousal and positive emotions, decreasing degree-of-arousal leads to weaker attention and more risk aversion in decision making in miners. In the high degree-of-arousal and positive emotions, with the increase of degree-of-arousal, the level of attention and risk aversion of miners in decision-making first increases and then decreases, until it is lower than neutral emotions. In low degree-of-arousal and negative emotions, decreasing degree-of-arousal would make miners pay less attention and have lower risk aversion in decision-making. In the high degree-of-arousal and negative emotions, an increase in degree-of-arousal increases and then decreases the attention and risk aversion in decision making, even until they are lower than the level of neutral emotions. By contrast, in the high degree-of-arousal range, increasing degree-of-arousal in positive emotion is more likely to reduce miners’ safety behavioral competence to lower than the level of neutral emotional.更多还原
